南非采购需求：碳钢管、钢管、钢管、碳管、碳管、ERW钢管

I'm looking for a carpet with dimensions of 12x6m. Could you please send me details about the available options? I'm particularly interested in the material types, colors, and any design patterns you might have. Additionally, I'd love to know about the durability and any maintenance requirements for the carpets you offer. It would be great if you could also provide information on pricing, lead times for shipping, and any possible discounts for bulk purchases. If you have samples or a catalog that showcases your products, that would be really helpful too. Looking forward to hearing from you soon!
